Always start with the SMTP log file. Look for any trace of communication between the remote domain's SMTP "spoke" to your SMTP. Also note what they "spoke" about. Review event logs. Work with telnet for communication testing. Review DNS records. Once you get some clues, you could do some google.com/technet.microsoft.com and of course msexchange.org :D Finally, you put the question here. :) We would then know how to solve your problem.
